In this earlier article, We saw how to get the lists having unique permission using C#. In the same manner, let us see, how to get the unique permission lists using PowerShell.

The script is straight forward and does not require much explanation.

 cls  #Import the required client dlls Import-Module   'C:\SATHISH\PRACTICE SOURCE CODES\Office365.Console\packages\Microsoft.SharePointOnline.CSOM.16.1.6420.1200\lib\net45\Microsoft.SharePoint.Client.dll' Import-Module   'C:\SATHISH\PRACTICE SOURCE CODES\Office365.Console\packages\Microsoft.SharePointOnline.CSOM.16.1.6420.1200\lib\net45\Microsoft.SharePoint.Client.Runtime.dll'  #Generic method to load the properties Function Invoke-LoadMethod() { param(    [Microsoft.SharePoint.Client.ClientObject]$Object = $(throw "Please provide a Client Object"),    [string]$PropertyName )     $ctx = $Object.Context    $load = [Microsoft.SharePoint.Client.ClientContext].GetMethod("Load")     $type = $Object.GetType()    $clientLoad = $load.MakeGenericMethod($type)       $Parameter = [System.Linq.Expressions.Expression]::Parameter(($type), $type.Name)    $Expression = [System.Linq.Expressions.Expression]::Lambda(             [System.Linq.Expressions.Expression]::Convert(                 [System.Linq.Expressions.Expression]::PropertyOrField($Parameter,$PropertyName),                 [System.Object]             ),             $($Parameter)    )    $ExpressionArray = [System.Array]::CreateInstance($Expression.GetType(), 1)    $ExpressionArray.SetValue($Expression, 0)    $clientLoad.Invoke($ctx,@($Object,$ExpressionArray)) }   #Mysite URL $site = 'https://sppalsmvp.sharepoint.com/sites/DeveloperSite/'  #Admin User Principal Name $admin = 'sathish@sppalsmvp.OnMicrosoft.Com'  #Get Password as secure String $password = Read-Host 'Enter Password' -AsSecureString  #Get the Client Context and Bind the Site Collection $context = New-Object Microsoft.SharePoint.Client.ClientContext($site)  #Authenticate $credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($admin , $password) $context.Credentials = $credentials  $list = $context.Web.Lists.GetByTitle('D1') $context.Load($list)    Invoke-LoadMethod -Object $list -PropertyName "HasUniqueRoleAssignments"  $context.ExecuteQuery()  Write-Host $list.HasUniqueRoleAssignments
